Description

Technical Field

[0001] The utility model relates to the technical field of transformer operation and inspection, in particular to a transformer respirator which is convenient for maintenance. Background Art

[0002] A transformer breather is a protective device connected to the transformer's oil conservator. Its primary function is to connect the air inside the conservator to the outside world. When the transformer is operating, the oil temperature rises, expanding its volume and exhaling air from the conservator. When the oil temperature drops, its volume shrinks, drawing in outside air, thus achieving equal pressure inside and outside the conservator. Furthermore, the conservator tank contains silica gel, which acts as an adsorbent to absorb moisture from the air, preventing it from entering the conservator and reducing the transformer oil's insulation strength. The bottom of the conservator tank contains an oil cup filled with transformer oil, which acts as an oil seal to prevent impurities from entering the conservator through the conservator.

[0003] After long-term use, the existing transformer breather needs to replace the silicone and oil seal inside it. When replacing, it is necessary to first remove the oil cup and then disassemble the silicone tank body before replacing the oil seal and silicone inside the oil cup. The operation is cumbersome and makes the transformer breather inconvenient to maintain. Therefore, in order to solve the above problem, a transformer breather that is easy to maintain is proposed.
